Clean windows are great, but who has time to wash them? There always seem to be more pressing tasks, not to mention more fun things to do. And then there are those windows that require ladders to reach -- with the associated risk of falling -- and those that are too high even for ladders.

So, how about a robot to do the job? Ecovacs Robotics thinks its Winbot 7 Series is the answer. It's easily used: You place spray cleaner on the cleaning pad on the back of the machine and place it on the window, where vacuum suction keeps it adhered. Then you push a button and off it goes, returning to the starting point when finished and "singing" a little song to let you know.

In addition to the cleaning pad at the bottom, there's a polishing pad at the top, and a scrubber in between, so it supposedly produces streak-free results. And the Winbot can sense the dimensions of the window and analyze the optimum path for cleaning it.

When the Winbot's done its work, you can toss the pads in the washing machine.
